Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an automated visual hot pressing device. Background Technology

[0002] During the mobile phone manufacturing process, the logo needs to be pressed onto the outer surface of the battery cover using a hot-pressing method, and the hot-pressing of the logo on the battery cover is achieved using appropriate hot-pressing equipment.

[0003] Among them, the Chinese invention patent with patent number ZL202421283246.X and patent name: A hot pressing fixture for mobile phone case logos, substantially discloses a logo hot pressing device; specifically, the hot pressing fixture for mobile phone case logos discloses the following technical solution: a hot pressing fixture for mobile phone case logos, including a base, several guide columns fixedly connected to the base, a support top plate fixedly connected to the upper part of the guide columns and located above the base, a movable plate slidably connected to the guide columns, and a drive... The movable plate has a sliding drive component, a base with a fixture for positioning the phone case, and a movable plate with a hot pressing head for hot pressing the phone case. The fixture includes a bottom mold fixedly connected to the base and a carrier placed on the bottom mold. The carrier has a protruding positioning boss that is inserted into the inner cavity of the phone case. The bottom mold has a protruding positioning pin fixedly connected to it. There are at least two positioning pins. The carrier has positioning holes for the positioning pins to be inserted. The movable plate is fixedly connected to a heat insulation plate, the heat insulation plate is fixedly connected to a heating plate, and the hot pressing head is fixedly connected to the heating plate.

[0004] During the hot pressing process of the phone case logo using the aforementioned hot pressing fixture, the phone case is first placed on the carrier, so that the positioning boss on the carrier is inserted into the inner cavity of the phone case. Then, the carrier is placed on the bottom mold, so that the positioning pin is inserted into the positioning hole, thereby achieving the positioning of the phone case. Subsequently, the driving component drives the movable plate to move down, and the hot pressing head presses against the back of the phone case to a certain depth to perform the hot pressing operation. After a certain period of time, the driving component drives the movable plate to rise and reset, so that the next phone case can be hot pressed.

[0005] It should be noted that the aforementioned hot-pressing fixture for phone case logos still has the following defects, specifically: Defect 1: During the loading of the phone case before hot pressing, the phone case is positioned on the carrier by the positioning boss, and the carrier is positioned on the bottom mold by the positioning pin of the bottom mold cooperating with the positioning hole of the carrier. Since there is a positioning gap when the positioning boss and the phone case are positioned and engaged, and there is also a positioning gap when the positioning pin and the positioning hole are engaged, the superposition of the above positioning gaps will affect the positional accuracy of the phone case during hot pressing, and thus affect the pressing positional accuracy of the LOGO. Therefore, this hot pressing fixture for phone case LOGO has the problem of low positioning accuracy and inaccurate positioning. Defect 2: The hot pressing fixture for the phone case logo cannot accurately control the pressing force of the hot pressing head on the phone case. Insufficient or excessive pressing force will cause the phone case to be scrapped. Therefore, the hot pressing fixture for the phone case logo has the problem of unstable pressing. Defect 3: This hot-pressing fixture for phone case logos cannot upload data to the MES system, nor can it inspect the hot-pressed phone case; its functionality is relatively limited.

Detailed Implementation

[0031] The present invention will now be described in conjunction with specific embodiments.

[0032] Example 1, as Figures 1 to 4 As shown, an automated visual hot pressing device includes a frame 1, a pressing head assembly 2, and a product platform 3. The pressing head assembly 2 is located on the upper side of the product platform 3. The pressing head assembly 2 includes a pressing head heating plate 21 and a LOGO pressing head 22 installed on the lower surface of the pressing head heating plate 21. The pressing head heating plate 21 is equipped with a first heating tube (not shown in the figure) and a first temperature sensor (not shown in the figure). The product platform 3 includes a product positioning carrier 31.

[0033] Among them, such as Figures 2 to 4 As shown, the pressure head assembly 2 also includes an X-axis drive linear module 23 mounted on the frame 1 and moving along the X-axis direction. The drive end of the X-axis drive linear module 23 is equipped with an X-axis movable seat 24. The X-axis movable seat 24 is equipped with a Z-axis drive linear module 25 that moves along the Z-axis direction. The drive end of the Z-axis drive linear module 25 is equipped with a Z-axis movable seat 26. The lower end of the Z-axis movable seat 26 is equipped with a pressure sensor 27. The lower surface of the pressure sensor 27 is equipped with a sensor connecting plate 28. The sensor connecting plate 28 is connected to the pressure head heating plate 21 through a heat insulation block 29.

[0034] Furthermore, such as Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 as well as Figure 10 As shown, a Y-axis drive linear module 41 that moves along the Y-axis direction is installed on the lower side of the product platform 3 on the frame 1. A Y-axis movable seat 42 is installed on the drive end of the Y-axis drive linear module 41. A horizontally rotating rotary module 5 is installed on the upper end of the Y-axis movable seat 42. The product platform 3 is connected to the drive end of the rotary module 5. The Y-axis drive linear module 41, the Y-axis movable seat 42, the rotary module 5, and the product platform 3 together form a product transfer assembly.

[0035] Furthermore, such as Figure 9 and Figure 10 As shown, the product positioning carrier 31 includes a product placement plate 311, a product placement area 3111 is provided on the upper surface of the product placement plate 311, and a plurality of spaced product positioning blocks 312 are installed on the periphery of the product placement area 3111 on the upper surface of the product placement plate 311; a negative pressure adsorption groove 3112 is opened on the upper surface of the product placement plate 311 in the product placement area 3111, and a negative pressure channel communicating with the negative pressure adsorption groove 3112 is opened inside the product placement plate 311. The negative pressure channel is connected to the negative pressure pipe of the negative pressure generator through a pipe joint.

[0036] In addition, such as Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 8 As shown, the frame 1 is equipped with a product vision inspection component 6 on the moving path of the product platform 3, the frame 1 is equipped with a pressure head vision inspection component 7 on the side of the pressure head assembly 2, and the front end of the frame 1 is equipped with a barcode scanner 9.

[0037] It should be noted that the frame 1 is equipped with a controller (not shown in the figure), and the first heating tube, the first temperature sensor, the X-axis drive linear module 23, the Z-axis drive linear module 25, the pressure sensor 27, the Y-axis drive linear module 41, the rotation module 5, the negative pressure generator, the product vision inspection component 6, the pressure head vision inspection component 7, and the barcode scanner 9 are electrically connected to the controller.

[0038] It should be explained that the controller in this embodiment is equipped with a temperature controller (not shown in the figure). The temperature controller is electrically connected to the first heating tube and the first temperature sensor of the pressure head heating plate 21. That is, the temperature controller is used to control the temperature of the pressure head heating plate 21.

[0039] The automated visual hot pressing equipment of this embodiment will be described in detail below with reference to the specific working process, which includes the following steps: Step a: Read and set the temperature of the pressure head heating plate 21 using the temperature controller; Step b: Scan the QR code of product 100 using barcode scanner 9. Product 100 can be a battery cover for a mobile phone. Barcode scanner 9 sends the product 100 information to the controller. The controller can communicate and connect with the backend server and upload the product 100 information to the MES system on the backend server. Step c: The staff places the product 100 in the product placement area 3111 of the product placement plate 311. During this process, the product placement plate 311 uses several product positioning blocks 312 to position the product 100 around its edges to ensure that the product 100 is accurately placed in the product placement area 3111 of the product placement plate 311. Then, the controller controls the negative pressure generator to operate and causes the negative pressure adsorption groove 3112 of the product placement plate 311 to generate negative pressure suction so that the product 100 is negatively adsorbed and fixed in the product placement area 3111 of the product placement plate 311. Step d: The controller controls the Y-axis drive linear module 41 to move. The Y-axis drive linear module 41 drives the rotating module 5 and the product stage 3 to move toward the product vision inspection component 6 through the Y-axis movable seat 42, so that the product 100 fixedly placed on the product placement plate 311 is moved to the vision inspection position of the product vision inspection component 6. At the same time, the controller controls the X-axis drive linear module 23 to move. The X-axis drive linear module 23 drives the Y-axis drive linear module 41, Y-axis movable seat 42, pressure sensor 27, and LOGO pressure head 22 to move toward the pressure head vision detection component 7 through the X-axis movable seat 24, so that the LOGO pressure head 22 is moved to the vision detection position of the pressure head vision detection component 7. Step e: The product vision inspection component 6 performs vision inspection on the product 100 that has been moved to the vision inspection position. The product vision inspection component 6 identifies the position of the product 100 on the product platform 3 and feeds back the position information of the product 100 to the controller. At the same time, the pressure head vision inspection component 7 performs vision inspection on the LOGO pressure head 22 that has been moved to the vision inspection position, and the pressure head vision inspection component 7 measures the position of the LOGO pressure head 22 and feeds back the position information of the LOGO pressure head 22 to the controller; Step f: After the controller obtains the position information of the product 100 on the product platform 3 and the position information of the LOGO pressure head 22 respectively, the controller controls the rotation module 5 to move. The rotation module 5 drives the product platform 3 to perform a horizontal rotation to correct the position of the product 100 on the product platform 3. Step g: The controller controls the X-axis drive linear module 23 and the Y-axis drive linear module 41 to move the LOGO pressure head 22 to the pressing position and to move the product 100 after position correction and adjustment to the pressing position. In step h, after the product 100 and the LOGO pressure head 22 reach the pressing position, the controller controls the Z-axis drive linear module 25 to move. The Z-axis drive linear module 25 drives the pressure sensor 27, sensor connecting plate 28, heat insulation block 29, pressure head heating plate 21 and LOGO pressure head 22 to move downward through the Z-axis movable seat 26, so that the LOGO pressure head 22 presses the product 100 on the product platform 3 downward. During this process, the pressure sensor 27 reads the pressure information of the LOGO pressure head 22 on the product 100 in real time and feeds the pressure information back to the controller in real time. When the pressure value of the LOGO pressure head 22 on the product 100 reaches the set value of the controller, the Z-axis drive linear module 25 stops moving and the LOGO pressure head 22 maintains pressure. Step i: After the holding time of the LOGO pressure head 22 is reached, the controller controls the X-axis drive linear module 23 and the Z-axis drive linear module 25 to move and reset the LOGO pressure head 22 to the initial position. The controller also controls the Y-axis drive linear module 41 to move in the opposite direction and move the product 100 that has completed the hot pressing operation toward the upper and lower parts position. Step j: When the Y-axis driving linear module 41 drives the product 100, which has completed the hot pressing operation, to move to the visual inspection position of the product visual inspection component 6, the product visual inspection component 6 performs visual inspection on the product 100, which has completed the hot pressing operation, so as to realize automatic visual inspection after hot pressing and judge the hot pressing quality. In step k, the Y-axis drive linear module 41 drives the product 100, which has completed the hot pressing operation and been inspected, to the loading / unloading position. The controller controls the negative pressure generator to stop operating. The worker removes the product 100, which has completed the hot pressing operation and been inspected, from the product placement plate 311 and enters the next cycle.

[0040] It should be emphasized that before pressing the logo onto the product 100 using the logo pressing head 22, this embodiment uses the pressing head vision inspection component 7 to identify and detect the position of the logo pressing head 22, and uses the product vision inspection component 6 to detect and position the product 100 placed on the product placement plate 311. Based on the position of the logo pressing head 22, the rotating module 5 is used to correct the position of the product 100 to ensure that the position of the product 100 and the position of the logo pressing head 22 are accurately matched when the logo pressing head 22 presses the product 100, thereby improving the accuracy of the logo hot pressing position.

[0041] It should be further emphasized that when the pressure head assembly 2 presses the product 100, this embodiment uses the pressure sensor 27 to acquire and detect the pressing force of the LOGO pressure head 22 on the product 100. When the pressure of the LOGO pressure head 22 on the product 100 reaches the set value of the controller, the pressure is stopped from being increased further. Compared with the prior art, this embodiment can accurately press the product 100 with a specified pressing force and has good pressing stability.

[0042] Furthermore, the automated visual hot pressing equipment in this embodiment reads the QR code of product 100 through barcode scanner 9, which can send and upload product 100 information to the MES system on the back-end server to realize product 100 pressing operation tracking.

[0043] In addition, after the logo is hot-pressed, the automated visual hot-pressing equipment in this embodiment 1 performs visual inspection of the hot-pressing quality through the product visual inspection component 6, which enables the automatic inspection function after hot pressing.

[0044] In summary, the automated visual hot pressing equipment of this embodiment has the advantages of novel structural design, high pressing position accuracy, and stable pressing force through the above structural design. It can also realize the function of uploading data to the MES system and the function of automatic detection after hot pressing, which can effectively improve the efficiency of LOGO hot pressing operation.

[0045] Example 2, as Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the product visual inspection component 6 includes a first CCD industrial camera 61, a first ring light source 62, and a gantry bracket 63 equipped with a frame 1 and located above the moving path of the product platform 3. The first ring light source 62 is located on the lower side of the first CCD industrial camera 61, and the first CCD industrial camera 61 is equipped with a first camera lens 64.

[0046] The first CCD industrial camera 61 is mounted on the gantry bracket 63 via the first fine-tuning module 65, and the first ring light source 62 is mounted on the gantry bracket 63 via the first light source bracket 66.

[0047] In addition, the first CCD industrial camera 61 and the first ring light source 62 are electrically connected to the controller.

[0048] When the product 100 on the product stage 3 reaches the visual inspection position of the product visual inspection component 6, the first CCD industrial camera 61 and the first camera lens 64 cooperate to acquire the image data of the product 100, and the first CCD industrial camera 61 sends the image data of the product 100 to the controller. The controller analyzes the image of the product 100 to determine the position or quality of the product 100 on the product stage 3.

[0049] Example 3, as Figure 5 As shown, the difference between this embodiment 3 and embodiment 1 is that the pressure head visual inspection component 7 includes a second CCD industrial camera 71 and a second coaxial light source 72. The second CCD industrial camera 71 is located on the lower side of the second coaxial light source 72, and the second CCD industrial camera 71 is equipped with a second camera lens 73.

[0050] The second CCD industrial camera 71 is mounted on the frame 1 via the second fine-tuning module 74, and the second coaxial light source 72 is mounted on the frame 1 via the second light source bracket 75.

[0051] In addition, the second CCD industrial camera 71 and the second coaxial light source 72 are electrically connected to the controller.

[0052] When the X-axis drive linear module 23 drives the LOGO pressure head 22 to the visual detection position of the pressure head vision detection component 7, the second CCD industrial camera 71 and the second camera lens 73 cooperate to acquire the image data of the LOGO pressure head 22, and the second CCD industrial camera 71 sends the image data of the LOGO pressure head 22 to the controller. The controller analyzes the image of the LOGO pressure head 22 to determine the position of the LOGO pressure head 22.

[0053] Example 4, as Figure 9 and Figure 10 As shown, the difference between this embodiment four and embodiment one is that the product platform 3 also includes a lifting movable plate 32 that is arranged horizontally and can move vertically relative to the drive end of the rotating module 5. The lifting movable plate 32 has a plurality of screw mounting holes 321 arranged in a ring array. Each screw mounting hole 321 is a stepped hole structure, and each screw mounting hole 321 is fitted with a limiting screw 33. Each limiting screw 33 is screwed to the drive end of the rotating module 5.

[0054] Among them, the frame 1 is equipped with lifting and unloading components 8 on the left and right sides of the moving path of the product platform 3, and each lifting and unloading component 8 is located below the lifting movable plate 32.

[0055] After the Y-axis drive linear module 41 moves the product 100 on the product platform 3 to the pressing position, the lifting and unloading components 8 on the left and right sides of the product platform 3 perform a lifting action to lift the lifting movable plate 32 upward and make the lifting movable plate 32 retract from the drive end of the rotating module 5. This can prevent the pressing force from being transmitted to the rotating module 5 during pressing and causing damage to the rotating module 5.

[0056] After the logo is pressed onto the product 100, the lifting and unloading component 8 moves in the opposite direction. At this time, the lifting movable plate 32 moves down, and the moving lifting movable plate 32 drives the product platform 3 and the product 100 that has completed the hot pressing operation to move down synchronously, so that the product 100 moves downward away from the logo pressing head 22 to achieve the unloading action.

[0057] Example 5, as Figure 11 and Figure 12 As shown, the difference between this embodiment 5 and embodiment 4 is that: the lifting and unloading assembly 8 includes a fixed base plate 81 installed on the frame 1, a lifting block 82 is movably installed on the upper side of the fixed base plate 81, and a contact block 83 is screwed onto the upper end of the lifting block 82; guide seats 84 are screwed onto the two sides of the fixed base plate 81 directly opposite the lifting block 82, and each guide seat 84 is provided with a vertically extending guide groove 841. The lifting block 82 is provided with a guide part 821 corresponding to each guide groove 841, and each guide part 821 of the lifting block 82 is slidably embedded into the guide groove 841 of the guide seat 84 on the corresponding side.

[0058] Among them, a movable push block 85 is horizontally slidably installed between the lifting block 82 and the fixed base plate 81. The fixed base plate 81 is equipped with a push block driving cylinder 86 corresponding to the movable push block 85. The driving end of the push block driving cylinder 86 is connected to the movable push block 85, and the push block driving cylinder 86 is electrically connected to the controller.

[0059] In addition, the movable push block 85 is provided with an upward protruding wedge-shaped protrusion 851, and the lower end of the lifting block 82 is provided with a wedge-shaped groove 822 corresponding to the wedge-shaped protrusion of the movable push block 85, and the inclined surface of the wedge-shaped protrusion contacts the inclined surface of the wedge-shaped groove 822.

[0060] When the lifting and unloading assembly 8 lifts the movable plate 32 upward, the push block drive cylinder 86 is activated and the drive end of the push block drive cylinder 86 drives the movable push rod to move horizontally. During this process, the wedge-shaped protrusion 851 of the movable push rod pushes the inclined surface of the wedge-shaped groove 822 upward through its inclined surface. Under the guidance of the guide seat 84, the lifting block 82 moves upward and causes the contact block 83 to push the movable plate 32 upward.

[0061] When the lifting and unloading assembly 8 performs the unloading action, the push block drive cylinder 86 drives the movable push rod to move horizontally in the opposite direction, thereby causing the lifting block 82 and the contact block 83 to move downward synchronously. During this process, the lifting movable plate 32 moves downward under its own weight and the weight of the product platform 3, thereby causing the product 100 on the product placement plate 311 to retract from the LOGO pressure head 22.

[0062] Example 6, as Figure 9 and Figure 10 As shown, the difference between this embodiment six and embodiment four is that the product platform 3 also includes a heat insulation plate 34 screwed to the upper surface of the lifting movable plate 32, and the product placement plate 311 screwed to the upper surface of the heat insulation plate 34.

[0063] A heating block receiving cavity 35 is formed between the product placement plate 311 and the heat insulation plate 34. The heating block receiving cavity 35 opens upwards, and the upper opening of the heating block receiving cavity 35 is located in the product placement area 3111 of the product placement plate 311.

[0064] In addition, the heating block accommodating cavity 35 is embedded with a product heating block 36. The product heating block 36 is equipped with a second heating tube (not shown in the figure) and a second temperature sensor (not shown in the figure). The second heating tube and the second temperature sensor are electrically connected to the controller.

[0065] In this embodiment six, the controller can control the temperature of the product heating block 36 through a temperature controller, that is, the second heating tube and the second temperature sensor are electrically connected to the temperature controller.

[0066] During the operation of the automated visual hot pressing equipment in this embodiment six, after the product 100 is fixed to the product placement area 3111 of the product placement plate 311, the product heating block 36 of this embodiment six comes into contact with the product 100. At this time, the product heating block 36 heats the LOGO pressing position of the product 100 to improve the heating efficiency of the product 100 before LOGO pressing.

[0067] Example 7, as Figure 10 As shown, the difference between this embodiment seven and embodiment one is that: the product placement plate 311 has a sink in the product placement area 3111, and a reflective photoelectric sensor 37 is embedded in the sink. The reflective photoelectric sensor 37 is electrically connected to the controller.

[0068] It should be explained that the reflective photoelectric sensor 37 in this embodiment is used to detect whether product 100 is placed in the product placement area 3111 of the product placement plate 311.

[0069] Example 8, as Figure 2 and Figure 3As shown, the difference between this embodiment eight and embodiment one is that the automated visual hot pressing equipment includes two pressure head assemblies 2 arranged left and right at intervals, two product transfer assemblies arranged left and right at intervals, and two product visual inspection components 6 arranged left and right at intervals. Each pressure head assembly 2 is equipped with a pressure head visual inspection component 7.

[0070] By setting up two pressure head assemblies 2, two product transfer assemblies, two product visual inspection components 6, and two pressure head visual inspection components 7, the automated visual hot pressing equipment of this embodiment eight can double the work efficiency.

[0071] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
